I posted a contest at my website about these...
Seriously, where do you even begin?
The flip-up sight: why would you put a flip-up "fast into action" sight on a gun? Either it's fast into action, or it needs to be flipped up. It can't be both.
The low profile sight: you realize they're taller than any suppressor sights on the market, right?
Overall I just don't get it. Apparently you're supposed to center the front dot inside the big oval when you need to take a fast shot but align the front dot with the rear dots when you need precision. At 7yd does anyone want to guess how high the gun is going to be shooting if you center the front sight in the rear oval? I'm guessing at least twelve inches.
I'm all for innovation. And I'm a lot more picky about my sights than most people, too, so I'm not criticizing people who want to find a better solution. But the world really doesn't need a bunch of people running around with sights that will essentially force them to miss the target, do we? Or will these be another of those they don't work in IPSC but they magically work great when someone is trying to kill you gimmicks?
